Cappadocia

Cappadocia is mentioned in the Biblical account given in the book of Acts 2:9, with the Cappadocians being named as one of the people groups hearing the Gospel account from Galileans in their own language on the day of Pentecost shortly after the resurrection of Jesus Christ. Acts 2:5 seems to suggest that the Cappadocians in this account were “God-fearing Jews”.

The Natural Rock Citadel of Uçhisar – is the highest peak in the region. It is completely honeycombed with ancient dwellings. Many of these spaces were used as cave monasteries, though today they mostly inspire photographers and artists. Its honeycombed architecture is revealed by erosion and suggests intense fortification and infrastructure.
